Yes, we recognize the ASB100 (with different ID) but treat it like
a as99127f.  This is working since 2.6.5; what version are you using?

Did you try FAQ 4.1.1?

Looks like mbmon touches the hardware directly... that's equivalent to
loading two drivers for the same hardware at once.  No suprise if they
get in eachother's way.  You could try to "rmmod" our modules including
i2c before you run mbmon... but even then I can't vouch for whatever state
in which that program leaves the hardware.  Any error in lm sensors that
you notice after running mbmon is out of our hands.

Yes, another a7v333 user mentioned this previously.  I thought he might
eventually submit a patch?  In the meantime, let's try to get everything
else working for you.  To start with, make sure you have at least the
2.6.5 i2c & sensors packages.
